New Data Read Access
In order to read out “new data,” i.e., to read out data that has been written in a follow-up manner, read reset must be
input after write address 150 and the difference between the read address and the write address must be 350 or
more but 1,114,111 or less.
Old Data Read Access
In order to read out “old data,” i.e., to read out data that was written prior to the write operation being carried out,
the difference between the read address and the write address must be 0 or more but 30 or less. If the difference
between the read address and the write address is between 31 and 349 or 1,114,112 or more, it is unpredictable
whether the new data is output or whether the old data is output. In this case, however, the write data will be written
normally.
